I'm not aware of anybody using it (even > testing it). I don't have hardware to test it (neither time). Could you maybe suggest a kernel patch to remove it, to see what happens? ... if nobody objects to the removal of the 32-bit MIPS KVM kernel support and the patch gets merged, that would help us in the long run, I think.
